Sure - it doesn't hurt to try. I reduced ALL my shift points and, all my TC lockup points by the maximum amount too. This only effects part throttle acceleration. It has no effect on WOT acceleration. I find that having the shift and TC lockups set the way I've done it, the truck seems to flow very nicely with other traffic, and I never try to beat anyone to the next light.

Alright so i went into the programming and changed my 3-4 shift (std shifting) to -2 and it did nothing for me.
The O/D doesnt kick in until 55mph and above. Should i worry about this or leave it alone? I drive alot of 40mph speed limits all the way to work and its not in O/D the whole way. ![]() I didnt see any TC options to set in there?

I think you are gonna need Bill to tweak your custom tunes at this point if you could not get the tranny where you wanted it with the changes you made

I'm VERY puzzled that you don't have Torque Converter choices in your Custom Options menu. As I recall, in my unit, it's the next choice below the shift options? You and I have nearly identical Gryphon's (your's might be a little newer - mine is a converted Edge). I think southpaw's right though, your custom tunes sound like they have the shift points way up in the rpm/speed curve (for more power) and I don't see how you're going to get the 3-4 upshift below 50. Bill CAN adjust those shift points down if it's really what you want. Even though I'm older than you, I don't really drive like a Grandpa. My truck accelerates easily with other traffic and I have no trouble accelerating faster if I want. I just had a thought though. What's your gearing and tire size? It may be that you really don't want the O/D on much earlier than it is. (As I recall, when mine kicks in and the TC locks, the RPM is about 1100, and you probably would not want it much below that). - Jack |

1100RPM? that's pretty low for a gasser... how far into the throttle do you get before it unlocks. I would think the engine would lug pretty bad if you tried any acceleration with the rpm's that low on a locked TC

Well i have the stock 20in rims from factory on my truck with stock tires.
Im not sure what that cooresponds to the gryphon becaus ei think i saw my tire size listed as 2760 i think- im not exactly sure by memory. my gear ratio i dont know that either off the top of my head but i think i saw it in the gryphon set as 3:73 I have a edge converted to gryphon as well Yeah around 50mph my rpms are at 1800 and once i hit 55mph i have to work at it to push it into O/D and then they go down to about 1200 rpm Yeah i have no option for TC control at all

So on my way home from work i decided to try something
I put the gryphon into level 2 programming (since that is a canned tune still) The truck shifted to O/D immediately at 45 mph and felt like how it was before. The custom tune must have been loaded and causing this problem- its locked until 55mph Bill is there something you can do to fix this for me ![]()
